Also seeMPEG Audio Compression basics which displays the MP3 frame Header particulars by means of an evidence that FF precedes the body Header and the body Header is I believe 32 bits (four bytes)contained by length (position zero to 31 or the primary four bytes after FF which you'll be able to see FF in the image contained by my previous put up). i don't know if they're massive or endian command. and i'm unsure that each one after the bit position 31 is bytes for MP3 compacted audio data.Firstly, the best way wherein an MP3 encodes knows that there will probably be sure frequencies that ear won't hear, and so it eliminates this knowledge. Secondly, ffmpeg is aware of that if there are thusunds which can be roaring, they will mask sure quieter correspondinglyunds, fittingly it removes the in view of thatund. lastly, it exploits the truth that ear confer on hear as a resultme frequencies higher than others. Its apiece tied contained by via the threshold of audibility.
